The basic features of functioning of different methods of compression of images are analysed. Classification of technologies of compact presentation of images is built. Methodological bases are expounded in relation to complex presentation of images. A comparison of different classes of technologies of compression is made in relation to the degree of compression and expenses of amount of operations provided by them on treatment. The problem sides of functioning of technologies of compression and regeneration of images come to light with the controlled error. Direction for development of new methods and technologies of compact presentation of images is formed with the maintenance of the set degree of authenticity of information.
